Vibration

[winddancer]

Is there anyone else out there that has had vibration in there bike that has cracked there Speedo faceplate this is the 2nd one that has cracked the lower half. also if anyone has some spare Speedo face plates that i could buy i am out of them. On another note i just changed my tires to the radials and man what a difference i wish this was the first update i did to my bike.

Mine has cracked all the way across right through the middle, but I 'm not sure if it was vibration that did it. I think it was the sudden stoppage from falling off the sidestand one early, drowsy morning, after pushing it out of the garage and turning for my jacket. After that is when I noticed the crack. 
Where can they be acquired?

I brought a new one when I rebuilt the bike some 9 or so years back, it now has a hair line crack about a mm or less on the upper side of the hole for the reset button only annoys me when the sun light hits from a certain angle and I remember that it's there

i had bought a used Speedo and that was the first one to crack so i pulled it off my old one so i was hoping some one might have some broken Speedo around and i would just pull the face plate and swap it.

My bike vibrates terribly, and I have cracked the speedo faceplate as you have.  (I have also vibrated the center cover off the needle, and my gauges all bounce crazily.)

Mine is probably long overdue for a rebuild, but you may also share my problem of broken  / missing lower mounting bolts, where the engine bolts to the frame with small-ish bolts through the footpegs. 

Good luck.

Good point on the small lower engine bolts, a common failure, but having ridden one with 3 of the 4 bolts missing or broken they don't contribute a lot to vibration. The biggest cause is seized front mounts.

A number of people here have given up when trying to remove the collars seems impossible.  DON'T GIVE UP. Do what ever it takes. It's worth it.

I have done 2 bikes, one came relatively easy, the other you'd swear had been cast as one part.

I ended up making 3 pullers, each one stronger than the last.

Puller Mk111 could have extracted the crankshaft through the exhaust pipe and with the help of much leverage I was able to apply enough torque to shift the earth's axis. Finally, with an almighty "crack" it let go. I expected to see half the crankcase and a couple of cylinders sitting on the floor.

Oddly enough, the difficult one was the low mileage bike that had never spent a night out in the weather in its life.

When done, and as previously stated, it will at first be disbelief at the improvement  then give way to a smile you can't get off your face.

You can now use your mirrors.

Just what you wanted, a crystal clear vibration free image of your shoulders.

Noel is right if you have 91+ I think, but all years sync the carbs!!!! These are the two leading causes of vibration. Hope this helps? If I am wrong on the years for the engine mounts please correct me.

My '93 has spent it's entire life well cared for and garaged.  The motor mounts were frozen solid.  Probably a result of too much washing.

Thought about this more last night and my engine mounts were not frozen, one was almost dry the other still had some grease on it. Still lubing them made a HUGE difference in the amount of vibration. I think this should be a annual maintenance item. Maybe next time I will install grease fitting like Noel.

 Thanks for all the response I had carbs sync about 4-6 months ago and I regularly remove the front mount and lube it with hi-temp grease. I am taking it to randy next week I might need to pull the engine and check the rears.

Have you had your carbs off or apart, done a valve adjustment or other maintenance since the carbs were synced?

About 6 months ago Randy rebuilt them
